I think Romney’s approach is the only approach that will work in a bi-partisan (we need to get rid of the two party system), and he has been successful with it as a Governor. You can’t show up with a plan that you think is perfect and try to ram it down everybody’s throat. It is the same on a tiny scale for me and my employees, you will not get what you want without everyone ‘buying in’ and feeling like they had a part in the decision making process. An added benefit of this is that everyone then feels some responsibility for success or failure.
As a good manager/leader/boss you have to know where you want to go, and then let your people help to decide the best way to get there.
